The Yukon coroner has determined a fatal traffic accident in Whitehorse in February was accidental.

Kirsten Macdonald says inexperienced driving may have been a contributing factor.

Jessica Behan, 18, died in the accident on Feb. 25. She was a passenger in a car that crossed the centre line of the Alaska Highway at Wolf Creek.

The car veered into the path of an oncoming pick-up truck.

The coroner found that Behan was not wearing a seat belt and the passenger side airbag did not deploy.

Road conditions, speed, alcohol or drugs were not factors in the accident.
